Answer:
-5.6
Step-by-step explanation:
Let the given function be g(x) = 2x - 1
To get g(-2.3), you will substitute x = -2.3 into the expression as shown;
g(x) = 2x - 1
g(-2.3) = 2(-2.3) - 1
g(-2.3) = -4.6 - 1
g(-2.3) = -5.6
Hence the value is -5.6
Note that the function was assumed. Same procedure can be applies for any function g(x).
